We have a dedicated thread for Multiplayer discussion here. Please have a look and post your comments there.
Also we won't be going into any details regarding why the decision was made to switch to matchmaking, because honestly it doesnt matter what we say about the subject. The fact is Matchmaking is here to stay and public lobbies will not be making a return.
We are currently working on adding new hoppers to the system, however with the increased load on our servers most of our networking team has been tied up working on stabilizing the system. We appreciate the patience, and understand the requests to add new hoppers.
Thanks,
